JOHN G. LAMONT, OF CHELSEA, MASSACHUSETTS.

RAIN-WATER CONDUCTOR.

SPECIFICATION forming part of Letters Patent No. 233,938, dated November2, 1880.

Application filed June 16, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN G. LAMONT, a subjectof the Queen of Great Britain, residing in Chelsea, in the county ofSuffolk and Commonwealth of Massachusetts, have invented an Improvementin Conductors, of which the following is a specification.

This invention has for its object the following-described improvement inconductors, reference being had to the accompanying drawings, formingpart of this specification, in explaining its nature, in which- Figure lis a perspective of a conductor, illustrating the features of myinvention. Fig. 2 is a section, illustrating one method of fastening theconductor to a building or any other structure.

It is desirable that a conductor should be expansible, in order that itmay not burst upon the freezing of water therein, that it be light andstiff, that it be ornamental, and that it be so constructed that it mayrest or bear firmly against the side of the building to which it isattached or upon any support to which it may be fastened.

In the drawings, A represents the conductor. lt'is made of sheet metal,and is provided with the outwardly-projecting folds a. The portion bbetween the folds preferably is made straight, although it may berounded in continuation of the remainder of the circumference of theconductor, if desired. The folds provide the conductor with thenecessary expansibility. They also act as feet or ribs for turnishin g asteady bearing or rest against the side of a building or upon anythingon which the conductor may be placed.

The seam o, uniting the two edges of the conductor, is preferablyarranged between the feet or folds a, although it may be made at the endof one of the folds.

I prefer that the uniting-seam be what is called a standing seam, turnedover and flattened, as represented in Fig. 1.

In making the conductor, a strip of flat metal of the requisite width isprovided with the necessary bends at either end for furnishing the seamand with the folds a, and itis then bent around a suitable former ormandrel and the two edges brought together and fastened.

The conductor shown in Fig. 1 may be secured in position by means ofametallic staple or loop, 0!, fastened to the conductor, and book (1,fastened to the building or other support to which the conductor issecured. It will be observed that this construction provides theconductor not only with a great range of expansibility, but that it isalso adapted to yield very readily to expansive pressure; also, that thefolds which provide the expansibility are in some instances caused to beused as feet or ribs for properly supporting the conductor.

I am aware that the patent to Conner and Koons, No. 127,850, shows anddescribes a cylindrical pipe provided with folds forming longitudinalflanges on the outside of the pipe; but I do not consider that said pipeso constructed meets the spirit of my invention also, that by arrangingthe folds and seams upon one side of the conductor and upon the sidenearest the wall or thing to which it is to be attached the metal usedis best disposed for stiffening the conductor.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States A metallic conductor, A, providedwith the outwardly-projecting folds a upon the rear portion thereof toact as feet or rests for furnishing a steady bearing, for strengtheningthe same, and for providing expansibility, all substantially asdescribed.
